Sp'eccation of Letters Patent.

Patented Oct. 21, 1913.

Application led April 16', 1907. Serial No. 368,569.

To all whom 'it may concern:

Be it known. that I, EDWIN K. CoNovnR,

a citizen ofthe United States, residing at' Paterson, Passaic county, inthe State of clear, and exact. specification.

My invention. relatesto improvements in motor vehicles, and thesame hasfor its objectl moreparticularlyy to -provide a! simple,

eieient and reliable, apparatus for actuatf..

ing` the brakes-of' the vehicle. n

Further said inventienhas for its object to provide an` apparatus forconveniently andeiiieientlyy operatingthat type or formof. brake whereina separate-device is provided for or adjacent to eachwheelon thedriving. shaft.

Further said lnvention has for its obj ect to provide an apparatuswherein the power applied to the brake'operating, apparatusy ormechanism willbetransmittf'adfl equally to the brake device ofeachwheel' in lorder that the retarding, force of said: brake deviceswill be caused to act upon each ofA said wheels in like manner and tothe'same degree.

" To the attainment of the aforesaid objects and ends my said inventionconsists in the novel details of construction', andin the combination,connection and arrangement of parts hereinafter more fully described andthen pointed out in the claims.

In the accompanying drawings forming part of this specieation, whereinlike numerals of reference indicate like parts, Figure 1 is a plan ortop view showing diagrammatically a motor vehicle frame and parts with abrake operating apparatus constructed according to, and embodying mysaid invention; Fig. 2 is a longitudinal section taken on the line 2-2of Fig. 1, looking in the direct-ion of the arrow a; Fig. 3 -is atransverse section taken on the line 3--3 of Fig. 1, looking in thedirection of the arrow b, and Fig. 4 is a section taken on'the line 4-4of Fig. 3 showing the manner of keying the several parts together.

In said drawings 10 designates the vehicle fra-me comprising thelongitudinal side members 11, 11 connected together by trans.

verse members 12, 12. Between the forward transverse members 12, 12 aresecured short longitudinal members 13, 13 upon which are mounted in thecustomary way a motor 14, and transmission 15. The forward end of theframe is mountedupon an axle 16 provided v, with steering wheels 17, 17,and the rear end of the frame is mounted, in the usual mannenupon adriving shaft 18 provided at its ends with wheels 19, 19 andV adjacentto -saidgwheels with brake drums 20,

20, 'providedwth operating levers 21, 21.

The vehicle asv above briefly described 1s of ordinary generalconstruction, and forms no part of my. invention. It is merely given inorder to more readily understand my in ventionl about to be described.

Upon the outer sides of the side .members 1111 adjacent to the drivingshaft 18 are lbolted,dependingA bearings 22, 22 in which .is supported atransverse shaft 23. Upon ,the outer ends ofl said shaft are keyed theupper. ends ofi depending arms 24, 24' which iare pivotallysecured'attheir lower ends to vthe upper endsof the brake levers 21, 21by -rods 25, 25. Upon. the transverse shaft 23 .intermediate thebearings 22, 22 is disposed bolt or key 28'wl1ichalso passes througnarecess 29 1n the shaft 23 and is secured 1n position by a nut 30. Uponthe outer end of said tubular member 26 is fixed the upper end of adepending arm 31.

Upon the underside of the frame 10 adjacent to its forward end isarranged transversely of the frame a short shaft 32 winch is supportedin bearings 33, 33 secured to the underside of one of the side members11, and the adjoining short longitudinal frame member 13. Upon saidshort shaft 32 1s fixed an arm 34 which extends upwardly therefrm,and'has its end pivotally connected to the end of the depending arm 31secured to the outer end of the tubular member 26 surrounding thetransverse shaft 23 by a rod 35, and 36 denotes a bell-crank leverhaving the end of its depending member secured to wthe short shaft 32,and the end of its upwardly extending member provlded with a foot plate37.

The operation of the apparatus 1s as follows: The brake mechanism properarranged within the cylinders or drums 20, 2O

los

is held normally out f engagement. As soon as power is applied tooperating mechanism due to the operator pressing down the bell-cranklever 86, the shaft 32 and arm 34 will be partially rotated, and the rod35 moved forward, together with the arm 31 on the tubular member 26carried by the shaft 23. As the inner end of the tubular member 26 issecured to the shaft 23 midway between its ends any force or powerapplied to said tubular member 26 will cause the same and the shaft 23to be simultaneously rotated, and the depending arms 24, 24 draw therods 25, 25 forwardly and partially rotate the brake levers 21, 2l andthereby actuate the brake mechanism proper contained in the-drums orcylinders 20, 20. As soon as the pressure upon the foot plate 37 isremoved the parts will be restored to their initial positions.

In the operation of the apparatus it is to be particularly noted that asthe power is transmitted from one side of the vehicle frame to themiddle of the shaft 23, the force with which t-he brake mechanisms areoperated is equal in degree or pressure, since whatever power` maybelost owing to the torsional strain on the tubular member 26 on the shaft23 is sustained equally by the opposite ends of the shaft 23 and thepower transmitted simultaneously from the ends thereof equally to thebrake mechanisms, and the same degree of frictio-nal engagement of thebrakes rendered uniform and alike at each side of the vehicle.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. In a` vehicle, the combination with 'a pair of brakes, of a shaftconnected at each of its ends with one of said brakes, an operatinglever, a sleeve surrounding said shaft and secured at one end to saidshaft midway between the ends thereof, and means connecting the otherend of said sleeve with` ing one end xed to said shaft at a point midwaybetween the ends thereof, and having its other end terminating adjacentto one of the ends of said shaft, a depending arm secured to the outerend of said sleeve, a short shaft supported upon the vehicle parallel tothe shaft first named, an operating lever and an upwardly projecting armsecured to said short shaft, and a link connecting saidupwardly-projecting arm with the depending arm on the sleeve surroundingsaid first named shaft, substantially as specified.
